REVISION OF LILAOPSIS. 
Crantzia Nutt. Gen. 1: 178. 1818; not of Scopoli (1777) and others. 
Lileopsis Greene, Pittonia 2: I92. 1891. 
The genus long known as Crantzia of Nuttall, and recently renamed 
Lilzopsis by Greene under the rule of homonyms, has such a charac- 
teristic habit that all of its forms have been merged into a single species, 
although earlier botanists proposed several. An examination of abun- 
dant material from different regions reveals several distinct types with 
well defined geographical areas. The following North American 
species seem to be worthy of recognition. 
* Fruit with lateral ribs prominently corky thickened, much more con- 
spicuous than the dorsal ones which are not at all corky. 
1. LILHopsis LINEATA (Michx.) Greene, 
Pittonia 2: 192. 1891. 
Hydrocotyle lineata Michx. F1. Bor. Amer. 
> 162. 1803. 
Crantzia lineata Nutt. Gen.1: 178. 1818. 
The Kew Index refers Hydrocotyle Chi- 
nensis L. to this species, which, if true, 
would require the use of the specific name 
Chinens?s.
